The world’s most powerful acoustic tractor beam could pave the way for levitating humans

Acoustic tractor beams use the power of sound to hold particles in mid-air, and unlike magnetic levitation, they can grab most solids or liquids. For the first time University of Bristol engineers have shown it is possible to stably trap objects larger than the wavelength of sound in an acoustic tractor beam. This discovery opens the door to the manipulation of drug capsules or micro-surgical implements within the body. Container-less transportation of delicate larger samples is now also a possibility and could lead to levitating humans.

Atoms can be in two places at the same time

Can a penalty kick simultaneously score a goal and miss? For very small objects, at least, this is possible: according to the predictions of quantum mechanics, microscopic objects can take different paths at the same time.  The world of macroscopic objects follows other rules: the football always moves in a definite direction. But is this always correct? Physicists of the University of Bonn have constructed an experiment designed to possibly falsify this thesis. Their first experiment shows that Caesium atoms can indeed take two paths at the same time.

Ekocycle 3D printer uses recycled plastic bottles as component in filament cartridges

Cubify has announced that it will be selling a $1199 printer later this year called the Ekocycle Cube 3D Printer-it will be using recycled PET plastic bottles as one component in its filament cartridges-a single cartridge will hold the equivalent of three 20oz. bottles, making up 25 percent of its content.
